Returning an Option<u8> to track the register index allows us to support parameter lists that are longer than 255 since we can return None instead of overflowing when we hit the the maximum value for u8. It looks like v8 supports 1000 params.

Thanks for the heads up @fitzgen; Winch is already compliant with those limits (via wasmparser), the limits that we're discussing are for ISA register counts.
